"Erratic 4 Untitled'' (acrylic on paper), by Mira Cantor, in her show "Erratics, works on paper by Mira Cantor,'' at Kingston Gallery, Boston, Nov. 1-26. The show is inspired by the forms of the same name created by the Ice Age and found all over New England, virtually all of which wascovered by ice 15,000 to 20,000 years ago. Ms.Cantor told the gallery: "These erratics are palpable forms of energy, eroding in slow motion."
